Abstract: In a method for stocking tool magazines of a device for machining workpieces, the device having at least a first spindle and a second spindle configured to be independently movable relative to one another at least in one axis, wherein the first and second spindles have correlated therewith at least a first tool magazine and a second tool magazine, respectively, workpiece machining is continued by the second spindle during stocking of the first tool magazine, and workpiece machining is continued by the first spindle during stocking of the second tool magazine. Alternatively, stocking the first and second tool magazines can be carried out simultaneously.

Abstract: A light-reflecting arrangement includes a stack of clean light-reflecting plates which are mounted on a support for gradual advancement, one after the other, into an operative position in which the respective light-reflecting plate replaces the previous one which may have become soiled while dwelling in its operating position, so that a relatively clean plate will be exposed in the operative position at all times to act as a reflector for oncoming traffic. The light-reflecting plates which have been replaced descend by gravity either to form another stack of used light-reflecting plates, or to be collected in a receptacle. The stack of the light-reflecting plates may be advanced by a pusher or by a threaded shaft cooperating with a threaded bore of the respective light-reflecting plate. The pusher may be advanced or the threaded shaft may be rotated by a spring-energized or a battery-energized motor, or by a drive which is energized by ambient pressure or temperature fluctuations.
